Abstract
Description
- The invention relates to a locking device, in particular of a motor vehicle, having a key and a lock cylinder, having a cylinder core, which is mounted in a rotatable manner in a cylinder housing and has a key channel into which the key can be introduced, having spring-loaded tumbler elements which are mounted such that, when the key is inserted into the key channel, they can be displaced radially to the cylinder axis of the lock cylinder, having several outer surfaces provided on the key, which have control tracks, which act on the tumbler elements when the key is introduced.
- A locking device of the above-referenced type is disclosed in
DE 10 2007 014 900 A1, wherein the key is embodied in each case with a control track on its two narrow sides as well as on its two broad sides. The referenced control tracks act on spring-loaded tumbler elements, which are arranged in the lock cylinder. It has been shown that tumbler elements of this type have proven useful in particular in connection with motor vehicles. In order to steal a motor vehicle, unauthorized persons try by means of break-in tools, for example by means of a so-called “picking system,” to sort the tumbler elements in the key channel to the cross-section of the cylinder core, whereby the tumbler elements release the cylinder core for rotation. - It has been shown that in some cases of use smaller installation spaces are necessary for locking devices of this type, wherein at the same time a high safety against break-in of the locking device must be ensured.
- To attain this object, a locking device with all of the technical features of claim 1 is proposed. Possible embodiments are suggested in the dependent claims.
- According to the invention, the outer surfaces of the key have two narrow sides and two broad sides, wherein each broad side is embodied with a first control track, the first narrow side has a second control track, and the second narrow side lying opposite the first narrow side is embodied free of any control tracks. One of the essential advantages of this locking device according to the invention is that, due to the second narrow side of the key embodied free from any control tracks, on the one hand the lock cylinder as well as the cylinder core with the key channel can be embodied in a smaller and more compact manner. Furthermore, a more compact key is created, which requires a smaller installation space in the lock cylinder.
- It can likewise be provided according to the invention that the tumbler element is embodied with at least one projection, which protrudes into the key channel when the key is not inserted, wherein the projection can be moved out of the key channel by the first or the second control track when the key is inserted, wherein in particular the tumbler element is embodied free from any projections on its side facing towards the second narrow side, in particular is adapted geometrically to the even, flat embodiment of the second narrow side. The control tracks hereby serve as a code track, wherein the code track is embodied with a profile that corresponds to the tumbler elements of the lock cylinder accordingly, that means that only the key with the correspondingly “correct” code track or code tracks causes a corresponding displacement of the tumbler elements out of the key channel in order to cause a movement of the cylinder core inside the cylinder housing when the key is inserted.
- Advantageously, the second narrow side forms an even area in its total extension of the key. Due to the flat second narrow side, which bears against one of the four walls of the key channel, a tilting of the key is reduced in a simple manner, whereby a much lower wear of the lock cylinder and the tumbler elements occurs with a repeated insertion and actuation of the lock cylinder with the key.
- One possible embodiment of the invention is that the first and/or the second control track is embodied as a control groove, wherein in particular the control groove has an essentially constant track width. Alternatively or additionally it is likewise conceivable that the first control track is a control groove and the second control track is a control rib. The control groove is hereby embodied in a concave manner, wherein the control rib is embodied in a convex manner on the outer surface of the key and its outer surface overlapped by the key.
- Advantageously, the key can be inserted in only one position in the cylinder core so that this is not a reversible key. Expediently, the key is a solid component, in which the control tracks are sunk. The key height can be further reduced by means of the measure of a narrow side free from any control tracks. Through the resulting possible reduction in size of the key channel, the lock cylinder is also more secure against break in, since with each reduction in size a potential break in tool must likewise be smaller in order to be inserted into the key channel and also the maximum force that can be exerted is reduced.
- Further measures and advantages as well as technical features of the invention are shown by the claims, the following description and the drawings. The locking device according to the invention is shown in detail in an exemplary embodiment in the following figures. They show:
-
FIG. 1 A perspective view of the shaft of the key of the device according to the invention, -
FIG. 2 A side view of the key according toFIG. 1 , -
FIG. 3 A diagrammatic representation of the lock cylinder into which the key according toFIG. 1 can be inserted and -
FIG. 4 A sectional view according to IV-IV fromFIG. 1 . -
FIGS. 1 through 4 show purely diagrammatically a locking device of a motor vehicle with akey 10 and alock cylinder 30, which is arranged in a vehicle door. Thelock cylinder 30 has acylinder housing 31, inside which acylinder core 32 is mounted in a rotatable manner. Thecylinder core 32 has numerous spring-loaded tumbler elements 41, 42. Furthermore, thecylinder core 32 is embodied with akey channel 33, in which thekey 10 can be introduced. - If the
key 10 is not inserted inside thekey channel 33, the tumbler elements 41, 42 protrude with their projections 41 a, 42 a into thekey channel 33 and at the same time block a rotation of thecylinder core 32 inside thecylinder housing 31, which is not explicitly shown in the drawing. In the present case, the tumbler elements 41, 42 are platelet tumbler elements. These tumbler elements 41, 42 are adjusted during the insertion of a proper “correct”key 10 such that the tumbler elements 41, 42 no longer protrude beyond the circumferential surface of thecylinder core 32, and thecylinder core 32 thus is rotatable in thecylinder housing 31. The user can thereupon unblock or block an actuation device of the motor vehicle by means of the locking device by a rotational movement of the insertedkey 10, depending on the rotational direction of thekey 10. A switch can likewise be actuated by means of the rotational movement of thekey 10, which switch activates and/or deactivates the ignition, voltage for the electronic components of the motor vehicle, etc. - As can be clearly seen in
FIG. 1 throughFIG. 3 , thekey 10 hasouter surfaces control tracks key 10 is inserted into thekey channel 33, act on the tumbler elements 41, 42 as well as on the projections 41 a, 42 a of the tumbler elements 41, 42. Theouter surfaces key 10 are embodied with twonarrow sides broad sides 13. Eachbroad side 13 has afirst control track 11, which is embodied as acontrol groove 11. That means that respectively onebroad side 13 is provided with respectively onecontrol groove 11. The firstnarrow side 14 is embodied with asecond control track 12, which is aprojecting control rib 12. Thecontrol grooves 11 and thecontrol rib 12 are furthermore equipped withfirst guide surfaces 16 as well assecond guide surfaces 17, which determine an individual topography of thecontrol tracks - The second
narrow side 15 of thekey 10 is embodied as an even surface, that means that, in contrast to the firstnarrow side 14 and the twobroad sides 13, the firstnarrow side 15 is embodied free of any control tracks. In the present exemplary embodiment thekey 10 is formed by a square flat profile, wherein the secondnarrow side 15 is aligned at right angles to thebroad sides 13. As can be clearly seen inFIG. 1 andFIG. 2 , thefirst control track 11 extends along the longitudinal extension of thekey 10, wherein thefirst control track 11 in some regions of thebroad side 13 can run up to thecommon edge 18 of thebroad side 13 and the secondnarrow side 15. As far as possible the entire height of thebroad side 13 can thus be utilized for thefirst control track 11, whereby the compact construction of thekey 10 is increased. - The
control groove 11 is furthermore embodied at thefree end 21 of the key 10 broadened in a funnel-like manner to theactual track width 19 of thecontrol groove 11 in order to thread thekey 10 more easily into thekey channel 33 of thelock cylinder 30. In the remaining course outside thefree end 21 of thekey 10, thecontrol groove 11 has aconstant track width 19 on both sides of thebroad side 13. The same also applies analogously to thecontrol rib 12, which likewise has an essentiallyconstant wall thickness 20, which can also be referred to as arib width 20. Of course, thetrack width 19 as well as therib width 20 can vary in different key sections, which is not explicitly shown. - As can be seen in
FIG. 3 , the tumbler elements 41, 42 which are supported in a displaceable manner inside thecylinder core 32, are embodied with at least one projection 41 a, 42 a. If thekey 10 is not inserted in thekey channel 33, as is shown inFIG. 3 , the projections 41 a, 42 a protrude into thekey channel 33. In the exemplary embodiment shown thelock cylinder 30 is equipped with two types of tumbler elements 41, 42. As indicated inFIG. 3 , a first tumbler element 41 of the first type can be displaced in a first radial direction 43 to thecylinder axis 34, wherein the first radial direction 43 of the projections 41 a which are located in the left region of thekey channel 33 is directed downwards. The first radial direction 43 of the projections 41 a which are located in the right region of thekey channel 33 is hereby aligned in the opposite direction. The second tumbler element 42 of the second type is displaceable in a secondradial direction 44, which is aligned perpendicular to the first radial direction 43. - The
first control track 11 hasfirst guide surfaces 16 and thesecond control track 12 hassecond guide surfaces 17. Thefirst guide surfaces 16 hereby act on at least one first tumbler element 41 as well as the projection 41 a. Thesecond guide surfaces 17 act analogously on at least one second tumbler element 42 as well as the projection 42 a. That means that during the insertion of thekey 10 over theprofiled guide surfaces radial direction 43, 44 and thus sorted inside thecylinder core 32 so that when thekey 10 is inserted a rotational movement of thekey 10 and of thecylinder core 32 inside thecylinder housing 31 is possible. - The tumbler elements 41, 42 are embodied free of any projections on the side facing towards the second
narrow side 15, that means that the tumbler elements 41, 42 in this region are geometrically adapted to the even, flat embodiment of the secondnarrow side 15. When thekey 10 is inserted, the secondnarrow side 15 bears directly against the adjacent, facingwall 33 a of thekey channel 33. - In the present case, the arrangement of the first tumbler elements 41 and the second tumbler elements 42 is arranged in alternating sequence. A plurality of first tumbler elements 41 and second tumbler elements 42 is hereby provided inside the
lock cylinder 30. - The control tracks 11, 12 described in the exemplary embodiment can of course be provided along the entire extension of the key 10. The extension lengths of the first and of the
